I agree with you there is some great material on babypips. The mentor I signed up with has a long thread on babypips too and gives his concepts and advice away for free on bpips. After I found him on here I decided to absorb his material which is why I signed up to his course. Im not going to name him!
In my opinion if you find a good mentor there are benefits to signing up to his course as opposed to exclusively staying on babypips. Apart from the course being structured the forums are relevant and to the point. Its easy for anyone to set up a free profile on babypips and sprout rubbish in order sell their wares. My mentors thread on here has been highjacked by others and has is becoming increasingly off topic and irrelevant. The course i signed up to his only half the price of nials.
To give nial his dues, he was my first taste of PA and in my opinion he is much better than all this indicator muck. I do like nials free articles on money management etc. I don’t look at his analysis anymore because i believe it to be a bit wishy washy. Its easy to see in hindsight why you should have taken the signal, but its not too apparent before hand.
